Endometriosis of the appendix

Abstract The clinical and pathological features of 6 cases of appendiceal endometriosis are reported. The appendix alone was involved in 3. The findings have been compared with previously reported cases. One of the largest deposits caused intussusception but otherwise the microscopic size of deposits did not correlate with symptomatology. The diagnosis may be suspected when the abdominal pain does not shift from the peri-umbilical region to the right iliac fossa in the manner of classic appendicitis and when the symptoms begin during or are exacerbated by menstruation.
